The halogens making up group 17 on the Periodic Table have seven electrons in their outer shell. The five highly reactive elements in this group are Fluorine, Chlorine, Bromine, Iodine, and Astatine.
What else can I help you with?
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
Elements with 5 to 7 valence electrons are called?
Well, some website said that it was in group Va, but what is group Va?
Do group 7 electrons have 7 electrons in the outer shell?
Yes, group 7 elements in the periodic table, such as chlorine and bromine, have 7 electrons in their outer shell. This makes them highly reactive because they only need one more electron to achieve a stable electron configuration.
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
Group of elements with 7 valence electrons?
Halogens
What is the number of valence electrons for group 2 elements?

The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.

Well, some website said that it was in group Va, but what is group Va?
Do group 7 electrons have 7 electrons in the outer shell?
Yes, group 7 elements in the periodic table, such as chlorine and bromine, have 7 electrons in their outer shell. This makes them highly reactive because they only need one more electron to achieve a stable electron configuration.
What p block has 7 valence electrons?
The group 17 of p block has 7 valent electrons. These elements are called halogens.
How many valance electrons does halogen have?
Halogens are group 17 elements. They have 7 valence electrons.
What are the elements that have the same number of valence electrons?
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
How many valence are in chlourine?
A total of 7 valence electrons. If I remember correctly, the number of valence electrons of all group A elements are designated by their group number. Chlorine is in group VIIA, hence 7 valence electrons.
